Drug Effects On The Thyroid

The effects of certain drugs on thyroid function can vary. For example, some medications, such as Lithium, Amiodarone, and Interferon alpha, can lead to hypothyroidism (underactive thyroid), while others, such as thyroid hormone supplements, Amphetamines, and drugs containing iodine, can cause hyperthyroidism (overactive thyroid). Additionally, certain medications, including Rifampin, Phenytoin, Carbamazepine, and Lithium can interfere with the absorption or binding of thyroid hormones, leading to changes in thyroid hormone levels. Drug-induced thyroid dysfunction can result in a range of symptoms, including fatigue, weight gain or loss, hair loss, and mood changes.
